Moore laid out five reasons why Trump would win on his website back in July. He wrote that Trump needed only to focus on blue states Ohio, Wisconsin, Michigan and Pennsylvania and noted his theory of "The Last Stand of the Angry White Man."

"There is a sense that the power has slipped out of their hands, that their way of doing things is no longer how things are done," Moore wrote. "This monster, the 'Feminazi,' the thing that as Trump says, 'bleeds through her eyes or wherever she bleeds,' has conquered us - and now, after having had to endure eight years of a black man telling us what to do, we're supposed to just sit back and take eight years of a woman bossing us around? After that it'll be eight years of the gays in the White House!"

Moore also expressed that many will vote for Trump "because they can" similar to when professional wrestler Jesse Ventura was elected governor of Minnesota.

He highlighted "the Hillary problem," in which he noted that the enthusiasm for Hillary Clinton "just isn't there" (particularly among millennials) and that Trump was getting more people off their seats and to the polls.

"Let's face it: Our biggest problem here isn't Trump - it's Hillary. She is hugely unpopular - nearly 70% of all voters think she is untrustworthy and dishonest," wrote Moore. "She represents the old way of politics, not really believing in anything other than what can get you elected."

And in his surprise live performance film Michael Moore in TrumpLand, Moore lays out how possible a Trump presidency could be. In the film, Moore talks about both candidates and included an imagined news segment depicting what would happen if Trump were elected, including the deportation of Rosie O'Donnell to American Samoa and aerial attacks on Mexican border towns.

"If you support Hillary Clinton and you've been doing this endzone dance and celebrating her early victory, you've been helping to defeat her by doing that," Moore said when he screened the film at New York's IFC Center in October. "There's a long tradition of Americans electing people you don't think they're going to elect. ... What the country doesn't need is to be told that Trump is a crazy, dangerous psychopath, sociopath, all of that. He has written and produced that movie and it appears daily."
